VoIP (Voice over Internet Protocol) is a technology that enables voice communications, such as phone calls, to be transmitted over the internet rather than through traditional telephone networks. By converting voice signals into digital data, VoIP allows users to make calls using computers, smartphones, or dedicated VoIP phones. This technology often results in lower costs, greater flexibility, and additional features like video calls and messaging. VoIP is widely used in both personal and business communications, offering a modern alternative to conventional phone systems.
